    "Worked perfect on my CM.028. I just had to grind down the screws a little bit because they were to long. Other than that I was successfully able to make an abomination of an AK-M16. God have mercy on me

    I bought this cause i think the gas tube on airsoft ak47's look rather cheap but i like the reliable version 3 gearbox, with this on and a 7" rail is magnificent.

    It fit snuggly into a ak47 cyma cm520 with a metal reciever

    You get a compact feeling when using the gun now, and i bought a rail seperately. That rail came with a steel tight nut, i installed it and there was a wrench slot so you could screw it down really good

    No wobble, nothing

    The hopup unit also sits better than ever

    I used this with the APS Stubby 5.5" Steel Outer Barrel for M4

    Would i recommend this item? Yes, solid piece of high quality alu
    It could take a beating when screwed down the rail nut, i used the matrix adapter as a place to hold when screwing on the nut, at the adapters weakest point it wouldnt give but just a tip, first install the adapter into the reciever before istalling the outher barrel just so you have the whole gun to hold on to when installing the nut

    Cons: The paint on the threads wore of a bit when screwing down the rail nut, i would recommend using some silicone oil to catch all the debris and wipe it of with a piece of cloth, it took 3 times screwing the nut in and out to really wear it in for a super snug fit but now there are no more paint coming of

    See no reason to give it a bad cred for how a seperate rail nut wore of some paint on the threads however
